i'm getting latitude and longitude of a location, I want to know the roads connecting to that location and whether it is land or water
I tried one google map api which is not helping to get the information i want.
http://maps.google.com/maps/api/geocode/json?latlng=40.7127,74.0059&sensor=true
Another SO answer pointed out two possible workarounds:
You can use Google Maps Reverse Geocoding . In result set you can determine whether it is water by checking types. In waters case the type is natural_feature. See more at this link http://code.google.com/apis/maps/documentation/geocoding/#Types.
You can detect waters/lands by pixels, by using Google Static Maps. But for this purpose you need to create http service.
You can use the Google Maps Geocoding API which does exactly that: http://code.google.com/intl/da-DK/apis/maps/documentation/geocoding Take a look at the "Reverse Geocoding" section

I've been trying to open Google Maps (specifically on Android, but not necessarily) from a coordinates URL, such as
https://www.google.com/maps/search/?api=1&query=51.5055,-0.0754
But when the map opens, I want it to show the location name such as "Tower Bridge". Not the coordinates 51.5055,-0.0754
I have tried something like
https://www.google.com/maps/search/?api=1&query=51.5055,-0.0754&query_place_id=Tower+Bridge
with no luck. When maps opens it shows the coordinates, not the place name.
I am okay with either "injecting" the location name (something like https://....&location_name=Traitors+Gate), and/or with maps revealing the location name (reverse geocoding) from the coordinates.
Motivation: Coordinates are more accurate and less ambiguous than location names. For example, there is Jerusalem, OH and there is Jerusalem, Israel, which is half a world away. Or, "Palais de Louvre" which is just one building but one huge building over four streets, with multiple entrances. Coordinates solve those issues, but they are not "Human readable". You can't present "49.3697,0.8711" to a user and expect them to recognise the Omaha Beach.
Thanks
Unfortunately, the Google Maps URLs doesn't support this kind of sending labels. You should send a valid place ID value in order to get correct title of the place in Google Maps app.
You will need one additional step to do this. Execute reverse geocoding request for coordinate and get a place ID.
https://maps.googleapis.com/maps/api/geocode/json?latlng=51.5055%2C-0.0754&language=en&key=YOUR_API_KEY
This will return a place ID ChIJlRsEuUgDdkgRSM7ciIhVooM of Tower Bridge. Have a look at this example in Geocoder tool:
https://google-developers.appspot.com/maps/documentation/utils/geocoder/#q%3D51.5055%252C-0.0754
There is a Java client library for Google Maps API Web Services that you can find on GitHub:
https://github.com/googlemaps/google-maps-services-java
You can use this library to execute geocoding requests, alternatively you can also use Places API nearby search to get the nearest place. Note that web services require a different API key, because they don't support Android app restriction that you use in API key for Maps Android API.
Once you get a place ID value just create Google Maps URLs link. E.g.
https://www.google.com/maps/search/?api=1&query=51.5055,-0.0754&query_place_id=ChIJlRsEuUgDdkgRSM7ciIhVooM
I hope this helps!
I need help with my final CS Project. Basically, I have to write an Android app that the user can specify a starting location and distance desired. It is going to generate a route that is exactly the distance of the input that the user can walk/ run and brings the user back to the starting location, using the Graph data structure and Google API.
I have my Google map and Android app but I’m not sure where to start with storing data using Graph ( I'm not sure if I should even use this data structure) and how to calculate the distance input. Any bits of advice/ help will be appreciated!
Okay your question is very tricky but still let me answer from what I got.
Use google map api, google places api, place picker or id and google maps json api for routes and distance.
let's take an example like you want walk or run 4kms from your places and comeback.
Case 1: if you want to opt for the same route from which you went to come back.
like you went from a-b then again you are coming bak from b-a.
for this case you can use Google maps geofencing and get the place inside a minimum raidus and make an algo to get the distance from your places.
if teh distance is half of the distance from your places then pick the most approximate place.
Use google maps json to get the places distance and google place picker for the location of nearby location object.
Case2: If you donot want to come from the same route through which you went
by, then select the nearest location object and get the longest route and follow
the same algo and procedure to get the distance.
I am working an Android App that displays bus route information when users inputs a route number.Is there any way i can fetch this information using google map's API??
As #VolAnd said, this question is very wide.
I found something that might help you if i understood you question correctly.
When user inputs a bus route number, you want to fetch route details( bus stops and timings).
Well for this you can use http://www.mybmtc.com/ search api.
You can check this link to know how to use it, but its in Python language.
... i can fetch this information using google map's API?? ....
If you want to search bus routes and show it on google map, then you can use google maps api's Direction service documentation. You need to specify travelMode as TRANSIT and TransitMode as BUS. You can specify all in between stops as waypoint[] in TransitOptions
So a quick answer,
Get and validate route number provided by user using mybmtc.com search.
That will give you details of all the stops on that route.
Use google maps Direction service to locate routes between origin and destination of that route.
You have to work hard for this.
Let me know if anything is missing.
In javascript, using Google maps apis we specify options such as google.maps.TravelMode.DRIVING. Do we have any equivalent for TravelMode in android? I couldn't see anything in android.location.LocationManager or android.location.Criteria
I've thought of following options:
Using some TravelMode alternative, get coordinates approximated to nearest street/road.
Alternatively, (Not preferred as it will be slow) get the coordinates normally and then probably send it to some google api(This will be pretty slow as there are many points) and get the coordinates corrected to the nearest street coordinates. Or in case if there exists some (google-maps) javascript framework, it may be used to get corresponding street coordinates.
Edit1:
I've also looked into this. and hence into android.location.Geocoder. The getFromLocation in this class seems to do most of the work. However, I'm afraid, of an additional delay while acquiring the nearest address.
If you are referring to Directions Service, then it uses Google Directions API internally as stated in the overview:
This object communicates with the Google Maps API Directions Service which receives direction requests and returns computed results.
As there is no native API for Android yet, I suggest using Directions API directly.
See my answer here.
I have a form in which user will type his address but i want to create such widget for address so that whenever user types his address, then all similiar location will be listed in the suggestion box and user can select his location.
Similiar functionality i have seen in google map navigation application.
Can you please tell me how create such feature?
If you are talking about matching places for a street address, this should work:
use reverse geocoding to convert it into (latitude, longitude) pair, both Android itself and Google API provides this service;
use Google Places API to obtain nearby places using the pair of coordinates
I have a project which actually does the similar job, while due to some reasons it is not public, but I can assure you this way could work.
Hope it helps.
